Still searching for that low cost but quality paintball and I may have found it. Used these in 95 degree (may have been hotter) heat and out of the 2000 rounds only had one break in the barrel. They pretty much flew to where I was aiming and I could see when they hit. My son complained that they bounced too much off of his targets, but I didnt seem to have too much trouble with that. Other players paintballs were bouncing off of me all day, figure the heat has a lot to do with that.
I'm not the biggest fan of yellow paint, (just my preference) but this yellow showed up quite well.

Conclusion:

For the cost we paid (and compaired to similar prices paint) I was very happy with these paintballs. I will be using them again.
